Dexamethasone with or without misoprostol to help start labor at term

Effect of Dexamethasone on Labour Induction in Term Pregnancies

Early Phase 1 Interventional Cairo University · NCT07109258

What this trial studies

This randomized, controlled early phase 1 trial at Cairo University Hospital enrolls nulliparous women at or beyond 39 weeks with a singleton, vertex pregnancy who are eligible for induction. Participants are randomly assigned to one of three groups: a single intramuscular 8 mg dose of dexamethasone, vaginal misoprostol 25 μg every 6 hours (up to four doses), or dexamethasone given with the first misoprostol dose. The primary outcome is time from initiation of induction to the beginning of the active phase of labor, with secondary outcomes including duration of active labor, second stage length, mode of delivery, and fetal outcomes. Clinical assessment includes Bishop score, fetal biophysical profile, and inpatient monitoring during induction as per protocol.

Who should consider this trial

Good fit: Ideal candidates are first-time mothers over 18 with a singleton, vertex pregnancy at or after 39 weeks who have no contraindication to vaginal delivery.

Not a fit: Women with contraindications to vaginal delivery (such as prior cesarean, placenta previa, non-vertex presentation), preterm gestation, fetal macrosomia, or significant maternal medical disorders are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the intervention could shorten the time from induction to active labor and may reduce prolonged inductions or emergency cesarean deliveries.

How similar studies have performed: Vaginal misoprostol is an established induction method, but using dexamethasone alone or combined with misoprostol for induction is relatively novel with limited prior evidence.
